ThinkPad T400 screen brightness/suspension

Q: ThinkPad T400 screen brightness/suspension

Hi everyone. I've a problem with mi Lenovo ThinkPad T400. The brightness is always at the minimum, and cannot be changed. But it is like when you close the laptop and the screens turns off, it is almost like that, I need a lantern to see what appears in the laptop, but besides that everything else works fine. If I connect it to an external monitor, then there is no problem, but you know, I don't wanna carry an external monitor with the laptop. Do you know how to deal with this? Thanks in advance!

I put my Thinkpad T400 in hibernate, but next morning I could not boot. When I press the power button, the lights below the screen turning on and I hear the sound of the hard disk, and the turns off. I do not even see anything on the screen; it is just black. The process keeps on repeating in a loop, unless I press the power button to turn off. I have tried the static charge removing trick. I have also removed the hard disk put it back again, but did not work either.  Please help.

I have a T400 ThinkPad upgraded to Windows 10 that suddenly had a blank screen and no lights except for wifi.On closer inspection I discovered the backlight is not lit during startup, whilst ThinkPad splash and window symbol are displayed but then, screen goes blank and then I hear the windows startup sound.Displays perfectly on an external monitor. I have replaced inverter, lcd cable and screen .... nothing works! I'm not sure if I should just resell the parts I bought and get another laptop .... can I transfer Windows 10 to another machine or is there another fix I could try? I don't have much money.Any help appreciated.

When opened fully (at right angle) the screen is blank. I can initially see a very dim Thinkpad logo on boot but nothing else, no BIOS, grub or luks screens. Also during this time the bluetooth LED on the inverter is on. The thinklight still works as does external display: If I move the screen down towards the keyboard the display comes on and I can see the screen as normal and other inverter lights come on such as the battery light.WHILE DISPLAY IS DOWN IN KEYBOARD   PLEASE ANY ONE SUGGENST ME WHAT SHOULD I DO?

Hi all, I would like to share my recent experience of Thinkpad X1 carbon (4th 2016) screen brightness problem, and how this problem been solved. The laptop cames good and the F5 and F6 function for screen brightness adjusting is OK. Other methods, like in the setting menu and battery menu,  to adjust the brightness are all OK.After one hour or one day or some short time, you will find you cannot adjust the brightness. Even the battery & power options are not working. The problem comes from the driver. First I thought it is the problem of driver of monitor (wide viewing angle high density flexview display 2560x1440 driver). I uninstall, update, change...but none of them work.Finally, I find it is the problem of intel hd graphics 520 . There is another evidence that during the time only this driver of intel hd graphics 520 has been updated automaticly to the latest version!So I uninstall and roll back to the version 20.19.15.4331 and the problem is solved.I did not check the lates version of this driver. But I am sure that the latest version of intel hd graphics 520 has conflict with the lenovo driver for screen brightness! I am sure there are other people face the same problem after the update of hd graphics 520 driver. Any engineer please check it!

I have just completed a clean install of Windows 7 Ultimate and all went well except for the screen brightness issue. Anyone have any ideas where I can simply increase this as I have searched everywhere for screen brightness, even BIOS for any setting for display. I have latest update to display driver. I have two other laptops and each shows much brighter than this one and I am surely disappointed in this display. Not sure if it is because this screen is touch enabled and also works off keyboard that could be the issue and a separate setting could be involved on the touch side of the display as it does work with a stylus pen or touch also. thanks and   I hope I can get this brightness to increase somewhat as it is too hazy for me.

The first and only bug so far I have encountered with my P51: Out of the box, the machine is set with the Hybrid mode in BIOS, meaning it switches between the Intel GPU and the Nvidia Quadro M2200 (Optimus). I want my machine to always use the discrete GPU, so I switch to Discrete mode in the BIOS. This however means that you can no longer change the screen brightness of the internal screen, it is always set at 100 %. Definitely seems like a driver bug. I have tried reinstalling Windows already, same result: With the Hybrid mode I can change the screen brightness, with the discrete mode I canīt.

I just changed my ThinkPad T450 laptop screen to a full-HD IPS display. The new panel (display) shows up in the Device Manager with Hardware ID MONITOR\LGD03FF. While the screen works, I can no longer adjust the brightness in Windows 10 - it's always on full brightness and the brightness key combinations no longer work (nor do any of the Windows 10 software brightness controls). The brightness adjustment keys work perfectly in Linux (Ubuntu 16.04), and they work if I go in to the BIOS. The monitor is showing up in the Device Manager as "Generic PnP Monitor". Any idea how to get brightness working in Windows 10 with the LGD03FF panel?

I recently upgraded my W700 to a clean Win7 Pro x64 install, downloaded the latest Win7 drivers from the Lenovo website, and did a manual install of all of them. Mostly there were no problems, however the OSD for mute, volume up/down, and brightness did not work. Here is the page for the Hotkey Features Integration package, which contains the OSD program: Hotkey Features Integration for Windows 8 (32-bit, 64-bit), 7 (32-bit, 64-bit), Vista (32-bit, 64-bi... The problem appears to be a bug in latest version of the OSD program, for the W700. I collected data on the various versions of the OSD utility; see below (I have used the overall package version as a reference, although the OSD program itself has a different version). Here is the fix: 1) Install the latest Hotkey Features Integration package. This gets the latest other packages, plus a broken version of OSD.2) Manually uninstall the OSD program (in Control Panel:Uninstall); reboot.3) Download and install the Hotkey Features Integration package version 3.85.0000. This is last version which works fully with the W700. Run the package installer, the run the installer itself. Make sure that only the OSD component is selected; run setup; reboot. That should fix it. It appears that the bug also exists in Win XP. Here is the info I have on the various versions: 3.33.0002 - OSD Works with W7003.81.0100 - OSD Works with W7003.84.2000 - OSD Works with W7003.85.0000 - OSD Works with W700 <&l...

A:thinkpad T400 Ram Upgrade

RAM: You need a minimum of PC3-8500 1066MHz DDR3. However faster chips like PC3-10600 1333MHz DDR3 or PC3-12800 1600MHz DDR3 will work fine as well.
 
If there's little or no difference in price I'd buy the faster memory. The reason is that if I upgrade to a new(er) notebook it's more likely the RAM will work at full speed on that system.
 
Note also that while you can upgrade to a maximum of 8GB (2x 4GB) with a 32-bit OS like WinXP-32 you won't be able to utilize more than 3GB.
 
SSD: Any of the drives you've listed will work well.

Hi, I've searched the forums and elsewhere online, and I can't find any real help for this issue. I'm running Win 7, and I have the most up-to-date drivers from the Lenovo site. I have turned on loudness equalization, but it has not helped the problem. This is an across-the-board problem. What I mean by that is, this problem persists regardless of the application, which I happen to be using. For instance, I use Media Player Classic: Home Cinema to watch movies. If the volume is at 0%, as I begin adjusting it upward, the volume level rises. However, as I reach about 70%, the volume stops increasing. There are audio adjustments w/in the application to boost the volume, but they serve to provide minimal effects. Overall, the volume is incredibly low. If you're sitting more than a few feet away from the laptop, it is inaudible. I don't know what else to do, and I was hoping that someone might offer some assistance. Thank you.  Jeff

Hi Punittiwari3353,
 
Welcome to Lenovo Community!
 

Have you checked it individually with battery and without battery?
Did you check with different power adapter or with different power socket?
Is the CPU fan running with regular speed?
Boot the system into ?Safe mode? and check if the issue persists there also?

Hope this helps. Do post back if the issue persists!

I honestly have no clue what could have caused this!  I turned it on this morning & it was stuck on the booting screen. It read "ThinkPad" in large letters followed by "To interrupt normal start up, press the blue ThinkVantage button." I waited for about a half hour for it to boot & it never did. I of course pressed the ThinkVantage button & to my dismay...nothing happened. Afterwards, I unplugged it & removed the battery pack. I then plugged it back in & attempted to start it up again. Once again, nothing. I unplugged it again & attached the battery pack. At that point I tried starting it up again and N O T H I N G!  What do I do?!

I have a thinkpad T400. Couple of months ago the problem started. I could not shut it down it just keep re-booting. I had to press and hold the start button to shut it. Now it won't boot at all. It beeps 1-3-3-1 and just sits there. When I press start button all lights come ON for a while and after only battery , AC and Ready lights stay ON. Here are few things I did so far without any luck: 1. Removed battery and AC adaptor waited few minutes put it back - same problem2. Removed CMOS battery. DIMM cards waited for ten minutes replaced - same problem tried with swapping  DIMM cards - when I put only one card on top slot it says put the card on zero "bottom" position. After placing the Mem card on the bottom slot no thing happens. It beeps again and sit. When I checked in the manual it says either DIMM or System board. I do not know which one is giving me the problem. I just do not want to replace all parts without knowing. Can any body help please or had similar issue and solutions if you managed to solve it. Thank you. Roshni

Now, I suspect that the inverters are fine and I'm wondering about the LCD switch or LCD cable. I suppose I could just buy a cable, but before that, I wanted to take a step back and try to figure out if I'm overlooking anything. I've not been able to find a picture or location of the t400 lcd switch in either the lenovo hardware manual for the t400 or elsewhere online.Hi,I've got a thinkpad t400 with CCFL backlight. I recently replaced a bad LCD (the backlight was working at the time) with a new one. However, while the new screen works, it's backlight did not. I ordered a new inverter and plugged that in - still didn't work. I grabbed the old screen's backlight and tried it with both inverters - did not come on. I then grabbed another laptop I have and plugged in the old screen's backlight - it came on. Plugged in the new screen's backlight (while lcd was still plugged into the thinkpad), it's backlight came on.So, I know both backlights are fine, and suspected I just had a crappy inverter. I got a replacement new inverter and it still doesn't work. Tried new lcd and old backlight with all three again, no dice. Backlights still turn on when connected to spare laptop. So I now suspect the inverters are fine. I noticed that the laptop no longer goes to sleep or hibernation when the lid is closed.

First, my t400 would only boot with power cord unplugged. Then it stopped booting altogether. I read to press the power button 10 times and hold it on the tenth time and to unscrew the palm rest to unplug the little battery for 30 seconds. That is the only way I can get it to boot now. I picked up a new regular battery today thinking it might be related but that hasn't solved it. Any ideas?
 

A:thinkpad t400 wont boot w/o reseting little battery behind palm rest

I looked at it closer and to get it to start i don't press the power button at all. I unplug the power cord and after unplugging the CMOS battery for awhile i just plug the power cord back in and it starts up. The first thing i see as it starts up is an error message about a bad CMOS checksum and then i have to change the date/time in the BIOS or it yells at me to do it. After all that it boots into windows 7. Once it is in windows no matter what i do to change the settings of what the power button does it still doesn't do anything. I can restart it fine but once i shut it down it the CMOS battery needs to be reset to get it going again.

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

On my IBM Thinkpad T43, the brightness controls no longer work. Pressing Fn+Home/End is supposed to lower/raise the setting, and it used to, but no longer does. It's also supposed to lower or raise the brightness depending on what power it is running on, but no longer does that, either.

I tried restoring to my original XP image, where it worked fine, but it still does nothing. Given that it used to work anywhere (BIOS, etc) I'm beginning to think it has nothing to do with XP's setup, but I can't seem to find a BIOS setting that makes a difference, either.

Any ideas?

Thanks,

Joe

I have disabled the adaptive display option on both my settings and the Intel graphics control panel, and yet my brightness still changes without my input. Any solutions?

Hi, I have a Thinkpad E550 and the built in display brightness looks too low. I have the latest video drivers for Windows 10 64bit. I first check the laptop brightness control typing the F6 key wich also have the brightness function, and the brightnes is set to 100%. Check with Windows 10 Setting App and also brightness is set to 100%. I check the battery/power setting and the "Enable adaptive brightnes" it off. Also check with the Lenovo Settings Metro App and the "Enable dynamic brightness control" is off. The resolution is set to native resolution in the case of this unit 1920x1080. Any ideas???

Hi, I can't adjust the screen brightness on my X250 at all. I have Windows 7 on it. When I press + and - the slider thing shows up, and it goes up and down, but nothing happens. It's really bright and have already been like this for weeks. The colour is slightly wrong as well. Restarting, shutting down or closing and opening the lid does nothing.It got stuck after I disconnected it from my docking station, so I tried connecting it and disconnecting again - nothing. I've updated Windows and nothing there as well. I'm getting really frustrated since nothing works.. Is there something to do? Please help..

I'm unable to adjust brightness on my lenovo thinkpad x230. I can't see the option in the control panel and the hotkeys for brightness dosen't work either.I've tried to install lots of dirrent intel video drivers and all the drivers I could find on Lenovos website. I've also tried to remove all drivers and carefully install them again one by one.I'm using Windows 7.Do anyone know what to do?

Hi all, I've been searching the forums about this topic, but I haven't found anything specific for my case: Symptoms: After turning on the laptop, the screen works fine for a few seconds and then it goes dark.The LCD display is working correclty, but with no backlight (still can see the screen if I use an external light source like a flashlight.All indicator lights (wifi, power, battery) work correctly.Image is displayed correctly if connected to external monitor.Problem happens in windows and BIOS (rules out driver issue).Realized that if I turn down the brightness all the way down and then press fn + F7 or if I close and open the lid, the screen would light up back again.If I turn the birghtness up, the screen goes dark again, but if I repeat step 4 it still works.After a few minutes of operating at minimun brightness, I can turn it all the way up and it won't go dark.Yesterday the backlight finally went out for good and not working at all.I'm trying to figure out if it's an issue with the inverter, mobo fuse or cable. Maybe someone here has seen these specific symptoms before and could lend me some knowledge and save me some time in debugging this issue. Thanks 

A:T400 no screen backlight

Assuming you have a CCFL screen (with an inverter), the inverter is most likely.  Some T400 have CCFL, some have LED.  With LED panel, it is probably bad panel.
